When the temperatures rise in La Quinta, CA, a ductless mini-split can keep you cool, but only if it’s in good shape. Banging, grinding, hissing. and buzzing noises are ductless HVAC noises that can can indicate a problem you should address immediately.
Banging
A banging noise could mean one or more of the system’s internal parts have become loose. For example, a loose bolt could rattle around during operation, or a misaligned fan blade could hit other components. No matter what component has become dislodged, ask a technician to handle the repair for you, ensuring that your unit won’t experience further damage.
Grinding
Bearings work to minimize friction, and if they deteriorate, the mini-split fan might make a grinding noise when rotating. Also, fan blades could make grinding noises if they scrape against other components due to a misalignment. In either case, a technician can inspect your unit, assess the situation and repair any damaged parts with new ones.
Hissing
If you hear a continuous hissing sound, call for professional services to ensure your safety and the efficient operation of your system. Refrigerant escaping through a small hole in the line can cause a hissing noise, as can issues with airflow or pressure. Please note that refrigerant has the potential to harm the environment and endanger people in your household, so act quickly.
Buzzing
While loose fan blades or other components could vibrate and make a low buzzing noise during operation, a problem with your electrical wiring could also result in this sound. The latter situation presents a more serious concern that could lead to a system malfunction, sparks or an electrical fire. For this reason, reach out for help whenever you hear buzzing coming from your system.
Banging, grinding, hissing and buzzing noises can signal issues that could affect the operation of your ductless system. If you need a service appointment for your ductless mini-split, reach out to Vic’s Air Conditioning.
